Corner Balanced the car yesterday. 04' GT

that makes more sense now...I was thinking to myself: how does my 40th anniversary only weigh 3060???

Might as well throw mine in here.
'06 GT with power seats, sunroof and 150-ish pound me in the driver's seat. 'Bout the same amount of fuel as you had. Hopefully I can get my hands on some scales again this spring after I move the battery and put a roll bar in.

Would you guys mind sharing what your ideal corner balance numbers are as far as front/rear percentages, left/right percentages, and cross weight (or LF-RR)?
All of my experience for chassis setup is with respect to dirt oval racing. I'm just beginning to dabble in road course setups with my RX8. Just curious where to start.
Thanks

I read somewhere that the Rex has a 51/49 weight distribution as you can see from the scales.
To get the car to rebound equally, i turned the dial one notch stiffer in the front. And from there I just up them all 3-5 turns at the track and back down again on the street. But now that I see those numbers, I could fine tune it a bit more. Thanks for the pics!

F/R is more up to personal preference and course design than L/R, in general a moderately powerful RWD car like ours should be at least 50/50, ideally more around 55-60% rear biased. The more potential for acceleration the car has (whether it's exiting a slower corner or just having more power), the more the rear bias will help, since more weight over the drive wheels results in more traction for them. It's a big part of the reason a 911 Turbo can get from 0-60 so quickly despite having similar power/weight to other, slower accelerating cars. Of course, you can easily give the rear too much weight and cause understeer and/or snap oversteer under throttle, so don't overdo it.
You may also want to adjust the suspensions attitude a little to match the changes, you will probably need to soften the front/stiffen the rear a bit to compensate for reduced traction up front.
A rear heavy car can also brake harder, since pitching the weight onto the front results in more even distribution than in a front-heavy or 50/50 car.

For the oval guy - 50/50 cross weight (ie wedge; ie LF+RR vs RF+LR) unless it's a track with heavy bias of important corners in one direction or the other.
The corners and Front/Rear, Left/Right sorta end up as they are what they are. If racing in a min weight class with some options for ballast placement you can address those things that way...
